30. The USDA doesn't have to set the guidelines

In contract law, courts have to answer riddles like this all of the time.

What will happen is that the defense will have its expert on the subject to testify about whether the beef was kosher, the plaintiff will have its expert on the subject to testify about whether the beef was kosher, and they will both do so for the purpose of allowing the court to determine what is the usual and customary practice in the relevant trade.

Next on the docket:

Probate Court:

"I leave my house to my son, provided he marries a Catholic before age 25, otherwise I leave my house to St. Alphonso's Pancake Breakfast Mission."

Okay, so, the kid has married a girl at at 24. He turns 25 and wants the house. St. Alphonso's goes to court because they don't believe she is Catholic.

Guess what the Probate Court is going to be figuring out in order to resolve that dispute?

These kinds of questions pop up all of the time, in a multitude of contexts.
